ADJUSTABLE MAP OR CHART STAND.

SPECIFICATION forming part of Letters Patent No. 461,755, dated October 20, 1891.

Application filed April 19, 1889. Renewed April 8, 1891. Serial No. 388,194. (No model.)

To all whom it may concern-.-

Be it known that I, HENRY E. HAYES, of-

-constructed as hereinafter described and in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a perspective rear view of the chart-stand in use. Fig. 2 isa detail, in vertical section, of the base-block with supportinglegs and vertical supporting-rod broken away; and Fig. 3 is a horizontal section on the line on x of Fig. 2.- Fig. 4. is a modification of a map-supporting bar. I

1 indicates a base-block cast with a downwardly-inclined outwardly-flaring flange 2 and internal sockets 3, with grooves 4 leading downwardly therefrom, in which rest the upper ends of the supporting-legs 5. The latter are held in place by a plate 6, attached to base-block 1 by means of a screw 7, passing through a washer 7 and hole Sin plate 6 and screwing into a threaded socket 9 in a lug 10 on base-block 1. The edge of plate 6 is form ed with cam shaped surfaces 11, which bear against the legs 5 and wedge against and tighten the latter in the grooves 4. The plate 6 is operated by means of lugs 12, whereby it can he turned to fasten or release the legs. The upper part of base-block l is formed with a socket 13, in which rests a vertical rod 14, of a suitable height to permit a frame for supporting charts to be adjusted to elevated position thereon, and on the'rod let is placed a sleeve 15, vertically adjustable thereon, and held in adjusted position by means of a setscrew 16. The sleeve 15 is formed with inclined socket projections 17, in which rest the lower ends of rods 18, their upper ends being bent at an angle, as shown at. 19, and projecting through holes in bars 20., held together by screws 21 and clamping between them a series of charts or maps 22. By raising and lowering the sleeve 15 and turning it on rod 14 the charts or maps suspended from bars 20 may be elevated to any desired position and moved to face and be disclosed in any desired direction.

By means of the cam-p1ate 6 the legs 5 will be securely held in position and may be readily detached. The stand may be easily and quickly taken apart and folded up compactly bydetaching legs 5 and rod 14 from basebloek 1, sleeve 15 from rod 14, rods 18 from sleeve 15, and bars 20 from rods l8.

In Fig. 4c is shown a modified form of mapsupporting rod formed of three pieces of wire, which consists of a central rod 23, having its ends bent to form loops 24: to engage the ends 19 of rods 18 and loops 25, through which slide the end rods 26, connected to rod 23 by their looped ends 27, which are adapted to slide on rod 23, and thereby adjust the length of the map-supporting rod. Sliding hooks 28 8c are mounted on rods 26, from which to sus pend maps of different widths.

Having thus fully described my invention, I claim as new and desire to secure by Letters Paten t- 1. An adjustable chart-stand consisting of a base-block formed with a socketed top and a downwardly inclined outwardly flaring flange, detachable legs having their upper ends resting against the base-block within the flaring flange, a rotary plate mounted on the base-block within the flaring flange and having cam-shaped surfaces on its edge, hearing against the legs, a vertical rod mounted in the base-block, a sleevehaving inclined 5 sockets and provided with a set-screw and movable on the vertical rod, rods mounted in the inclined sockets, and means for supporting a chart or map-file from said rods, substantially as shown and described.

2. In a chart-stand, the combination of a base-block formed with a socketed top to receive a vertical rod, a downwardly-flaring flange and internal recesses for the upper ends 4. In a chart-stand, a base-block 1, formed with a socket 13 in its top to receive a vertical rod, a downwardly and outwardly flaring flange 2, internal sockets 3, with grooves 4; in flange 2, legs 5, resting in sockets 3 and grooves 4, and a rotary plate 6,with lugs 12 and camshaped edges 11, bearing against legs 5 and mounted on base-block 1, substantially as shown and described.
